PORTABLE OVEN.

SPECIFICATION forming part of Letters Patent No. 711,285, dated October14, 1902.

Application filed February 21, 1902. Serial No. 95,102. (No model.)

To rbi/Z whom, t may concer-71,:

Be it known that I, JOHN R. CARTER, ofAugusta, in the county of' Brackenand State of Kentucky,have invented certain new and useful Improvementsin Portable Ovens; and l do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in portable ovens, the object oftheinvention being to construct a sheetmetal oven of this character ofas few parts as possible and at the saine time to construct an oven ofneat and attractive appearance, strong and durable,and air-tight,(asfaras it is desirable to so make an oven having an open bottoni 5) andwith this object in View the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in elevationillustrating my improvements with the door open. Figs. 2 and 3 are viewsin section of the same. Figs. 4, 5, and 6 are detail views of theseveral blanks, and Figs. 7 and S are views illustrating a modified formof my improvements.

1 represents the blank from which the top, sides,and bottom are formed,2the blank forming the back, and 3 the blank strip to be secured to thelower edge of the front.

In constructing the oven the blanks above mentioned are first formed andblank 1 slit, forming flanges at both edges,and the blank is then benton the dotted lines of said Fig. 3, forming a rectangular casing,comprising the top, sides,and bottom,which latteris made with anopenings and is secured by rivets or otherwise to a flange 5 on thelower edge of one of the sides. The fianges 6 at the rear of the top,sides, and bottom are bent at an angle, and the flanges 7 on the blank 2(forming the back) are placed thereagainst, and said fianges doubleseamed and flattened against the back. The flanges 8 on the front edgeof the top, sides,and bottom are bent inward, overlapping each other attheir ends,

5o the flanges at the upper corners of the oven beingpreferably rivetedtogether,and to the lower portions of the flanges on the front edges ofthe sides and to the flange on the bot.- tom the strip or blank 3 issecured by rivets. Adoorof any approved construction is hinged to thefront to close the opening therein, and a suitable deflector is locatedin the oven to deflect the heat entering through the open bot tomthroughout the entire oven.

In Figs. 6 and 7 Ihave illustratedaslightlymodified form of myinvention, in which the blank 14 comprises only the top and sides and isflanged at each end and bent inward, as shown at l5, forming a portionof the bottom. The rear portion of the bottom is formed by a flange 16on the back secured to the flanges l5, and the front portion of saidbottom is formed by a blank 17, bent longitudinally and secured at thelower front corner of the casing, forming a portion of the bottom andthe lower closed portion of' the front. The back is secured to theflanges at the rear of the top and sides by double-seaming'and attenin gthe seam against the back, as above explained, and in all other respectsthis form of my invention is like the preferred form described. y

A great many other slight changes might be resorted to in the generalform and arrangement of the several parts described Without departingfrom the spirit and scope of my invention, and hence I would have itunderstood that I do not limit myself to the preoise details set forth,but consider myself at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. An oven-casing comprisinga sheet-metal blank bent to form the top andsides of the casin g and fianges at the front and rear edges of said topand sides, a back having a flange at each of its edges, all of saidflanges on the back secured to the flanges at the rear edges of the topand sides, fastening devices securing the fianges at the front of top ofthe oven to the fianges of the sides, a separate strip connecting thelower portion of the side at one end to be secured to the bottom,flanges 1o at the rear of said top, bottom and sides, a back, Iianges onsaid back seamed to said first-mentioned flanges, anges on the frontedges of the top, sides and bottoin, the top flange being secured to theside flanges and a strip secured at its ends to the lower portion of theside anges and partially closingv the opening in the front of thecasing.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

JOHN R. CARTER.
